Considering I work for the Govt -that answer is good enough for govt work --- actually I had forgotten about the sub at Mobile until you mentioned the one in Galveston -which I did not know about.

Trivia time -not a question - but there is a USS South Dakota memorial/monument in South Dakota -it is a park in Souix Falls ... features an outline of the ship ... think I would rather see the 3d things -but a thoughtful gesture none-the-less.
